polar transformation

Is there a way to convert a complex function to its polar form easily? Say, a+bi >> sqrt(a^2+b^2) angle: atan(b/a) Also, is there an easy way to find and assign a variable the conjugate of the complex function (without having to retype all the way) attached is a simple problem (err solution) which i made. notice that i have to rewrite just to get the conjugate.. and i can't outrightly transform it to phasor.. thanks..

Yes. Go to Help and search for the word 'polar'. From the results, select the page 'functions for complex numbers'; this describes the arg function and modulus function. Then goto the linked Quicksheet "Complex Numbers: Polar Notation". This gives examples of their use and gives a pair of (user-defined) functions that handle transformation between the polar and rectangular forms.

You can get the complex conjugate by using the built-in conjugate operator (key stroke " in M13).

As an aside, it is generally better to post a worksheet rather than a pdf file - save somebody the effort of typing in what they see and 'print outs' can mask subtle errors, such as implicit multiplication or incorrect choice of index type (ie, index v literal). Ideally, post the worksheet in the version you use and the earliest version Mathcad will let you save as (the latter gives you a much wider audience as Mathcad worksheet format s are not generally backward compatible), eg Mathcad 11 will not read Mathcad 13 xmcd files).
